Re: freebsd - mbuf clusters!!!

Number of mbufs is calculated based on

nmbufs = NMBCLUSTERS * 4;

To increase them, add..

options "NMBCLUSTERS=8192"

to kernel conf and recompile.

The default is calculated based on..

NMBCLUSTERS = (512 + MAXUSERS * 16)

I suspect that this is only an initial static value. It may grow dynamically
as many variables in freebsd do. If this is the case, you may be short on
memory.
